Description
Kotone Aizuhara, a male university student from modern Japan and self-identified fudanshi with a passion for boys' love fiction, meets an abrupt end when a truck collision buries him beneath a pile of BL manga at a bookstore. This event transports him to an alternate world devoid of women, where he awakens within an ancient Asian-inspired palace setting.

In this realm, he encounters Nagi, a divine serpent entity in human form. Nagi declares Kotone his destined bride, or "Miko," explaining their compulsory sexual union is necessary for his ascension to a higher dragon form. Recognizing the scenario's parallels to BL narrative structures, Kotone anticipates his role as the receptive partner. He resolves to wield his extensive knowledge of BL tropes and character dynamics defensively, aiming to avoid emotional entanglement and maintain personal agency.

His background as both an avid gamer and consumer of fictional narratives shapes his approach. He instinctively analyzes situations through the lens of genre conventions, strategizing interactions based on his understanding of common BL character archetypes and plot devices. This analytical perspective serves as his primary coping strategy amidst the unfamiliar societal structures and supernatural elements of the new world.

The setting imposes unique social dynamics, being exclusively male-populated with relationships between men forming the foundational societal structure. Within this context, Kotone interacts with multiple characters beyond Nagi, including figures such as Wu, Kagetora, Haruka Sakuraba, Hao, Yua, and Jiru. These interactions contribute to his ongoing adaptation and responses.

Across various narrative media installments, his relationship with Nagi evolves beyond its initial transactional premise, developing increasing complexity. While early interactions focus on Kotone's resistance to predetermined roles, later developments show gradual shifts in their dynamic. His expertise in BL tropes remains a consistent aspect of his characterization, utilized to interpret and respond to interpersonal challenges.

Drama CDs and additional animated installments further explore his interactions within this world, reinforcing his identity as a fudanshi while demonstrating his adaptation strategies. These supplemental materials maintain continuity in portraying his application of BL genre knowledge as a survival tool within the supernatural and socially unfamiliar environment.
